Sun set/raise time data obtain element 8 store the sunrise time corresponding with longitude and latitude and Sunset time.Sun set/raise time data obtain element 8 provide about with obtained by navigator 5 Sunrise time that longitude shown in gps data is corresponding with latitude and the information of sunset time.Due to day Going out sunset time data is the normal data corresponding with longitude and latitude, it is therefore preferred to consider by The light shield effect at the sunshine that the barrier being arranged between the current location of vehicle and the sun produces.Barrier Thing is hindered to be arranged on the day outgoing direction and sunsetting from vehicle viewing.Such as, it is arranged on high mountain at vehicle Time in region, preferably consider to be positioned at the light shield effect of the high mountain of vehicle periphery.Arrange at vehicle Time in urban area, preferably consider to be positioned at the light shield effect of the building of vehicle periphery.This Outward, even if when solar energy photovoltic power system is arranged in same area, owing to irradiating solar photovoltaic What the irradiation time section of the illumination of electricity generation system was likely to be dependent on solar energy photovoltic power system arranges position. Thus the irradiation time section of solar energy photovoltic power system can be inputted by user.

Being charged battery 4 in user's instruction with once whilst on tour on preparing, user is at plug-in type car Multiple charging terminals 9 of 1 are connected to the electric work from solar energy photovoltic power system and commercial power source Under conditions of rate circuit, navigation device 5 inputs about the information travelled next time.Navigator 5 with It is charged scheduling based on the time started of input and destination, and then navigator 5 starts Battery 4 is charged.

Fig. 2 shows the flow chart representing the charging process performed by navigator 5.Navigator 5 The residual capacity of battery in charge controller 2 is checked in step A1.It follows that in step A2, Charge controller 2 calculate be used on next day or future time on the required electrical power once driven Amount.

Fig. 3 shows the flow chart of the calculating for the required amount of electrical power driven next time.In step In B1, charge controller 2 determines whether user is provided with the time of advent of such as destination and estimation Route.Charge controller 2 determine user be provided with in navigator 5 on once drive During route, i.e. when the judgement of step B1 is "Yes", navigator 5 calculates from current location to mesh The best route on ground.Additionally, navigator 5 with the distance between current location and destination and Calculate in current location and destination based on data about Fuel Consumption and/or electric power consumption amount Between back and forth advance needed for required amount of electrical power Y.In this case, from current location to mesh The best route on ground when being the route that vehicle once ran over, by by factor of safety and reality at that time Border electric power consumption is multiplied the estimation of the best route that obtains between current location and destination Electric power consumption amount.Although the best route once driven on being used for be vehicle once along its from work as During the route that front position travels to destination, the past data consumed by the actual electric power of this route is used Make the electric power consumption amount estimated, but when vehicle did not also travel along this best route in the past Or when vehicle travelled partially along this best route in the past, navigator 5 calculates under being used for The electric power consumption amount of the estimation once driven.Specifically, navigator 5 at vehicle in mistake Go along best route a part travel time by utilizing the actual electric work of a part for this best route The past data of rate consumption calculates the electric power consumption amount of estimation.Vehicle the past not along When the other parts of this best route or whole best route travel, navigation system 5 is by utilizing ground Sideways inclined angle in diagram data and the data of the existence etc. of traffic lights calculate the electrical power of estimation and disappear Consumption.Here, sideways inclined angle is upward slope or the angle of inclination of descending of road.Specifically, When best route includes going up a slope, navigator 5 is by the electricity when vehicle travels on flat road Power consumption increases to calculate according to the amount of electrical power of sideways inclined angle and the distance estimations of upward slope to be estimated The electric power consumption amount of meter.When optimum line includes descending, navigator 5 is by the electricity that will estimate Power consumption reduces the amount of electrical power regenerated and calculates the electric power consumption amount of estimation.At optimum line During including many traffic lights, electric power consumption amount increases greatly due to the quantity stopped.Thus, navigation Equipment 5 increases, by the quantity according to traffic lights, the electric power consumption amount estimated and calculates the electric work of estimation Rate consumption.Additionally, navigator 5 by consider speed in this route limit, the number of runway Amount, the distance of linear road, drive the traffic of day or next driving time etc. at the prediction next one When blocking up, the distance of traffic congestion is to calculate the electric power consumption amount of estimation.Additionally, at best route bag Include tunnel, or next driving time include after the sunset evening hours time, need to turn on lamp, And the electric power consumption amount therefore estimated increases.

Then, navigator 5 calculates the time of advent and the institute of estimation based on route calculation result The driving time needed.Navigator 5 was come based on the time of advent estimated and required driving time Estimate the time started.Such as, the time of advent of estimation is point in the morning 9, and required driving time is one Individual hour, and the required amount of electrical power of round trip for arriving at is 50KW.Here, When being located in charge for battery 4 in purpose, user arranges one way route in navigation system 5, And in this case, it is necessary to amount of electrical power be the half of round trip.

User use vehicle 1 as travel frequently vehicle time, destination is identical, and best route is identical. Thus, readily estimated required electric power consumption amount.It is used for work of travelling frequently to lay in the electricity of vehicle 1 Required and the sufficient amount of electrical power made or go to school, navigator 5 can be on the screen of a display Including the charge switch for (not shown) of travelling frequently.Thus, by only pressing a button, i.e. use In the charge switch travelled frequently, user easily arranges and drives chance next time is to travel frequently.Therefore, in step In B3, navigator 5 determines whether user opens the charge switch for travelling frequently.In navigator 5 determine when user opens the charge switch for travelling frequently, i.e. when the judgement of step B3 is "Yes", Navigator 5 in step B4 with some day, weather forecast and the actual electric power consumption of one week Required amount of electrical power is calculated based on past data.In this case, relative at Commuting Distance In short-term, and the most only by solar energy photovoltic power system just can adequate preparation must amount of electrical power time, Charge controller 2 can be controlled only using solar energy photovoltic power system from sunrise to time started Battery 4 is charged.In this case, charging cost is minimum.

Destination in input is located relatively near current location, and/or the time started of scheduling is the most late, Make only by solar energy photovoltic power system just can adequate preparation required amount of electrical power time, owing to filling Electric controller 2 can be controlled only using solar photovoltaic generating from sunrise to the time started dispatched Battery 4 is charged by system, and therefore charging cost is minimum.Even if only passing through solar photovoltaic generating When system is with regard to amount of electrical power that adequate preparation is required, it is preferred that period by day, i.e. little at sunshine Time during, farthest use solar energy photovoltic power system that battery is charged.

When user is not provided with route, i.e. when the judgement of step B1 is "No", and user does not has The judgement having the charge switch opened for travelling frequently, i.e. step B3 is "No", then navigator 5 with Estimate based on calendar whether user uses the vehicle for travelling frequently.Specifically, in next sky it is During working day, navigator 5 assumes that user uses for the vehicle travelled frequently at next driving time. When next sky is day off or holiday, owing to user will not use vehicle to be used for travelling frequently, therefore fill Electric controller 2 is controlled being fully charged battery 4.

It follows that in step A3 of Fig. 2, navigator 5 prepares charging operation plan.

Fig. 4 is the flow chart of the preparation process of charging operation plan.Navigator 5 is true in step C1 Determine whether user arranges the time started of scheduling.Determine that what user setup dispatched opens in navigator 5 During time beginning, i.e. when the judgement of step C1 is "Yes", equipment 5 obtains next sky from information centre Or the weather forecast of future time, and it is fine to determine that in step C6 this weather forecast indicates whether Weather.When weather forecast represents fair weather, i.e. when the judgement of step C6 is "Yes", navigation Assume based on the equipment 5 table data in the equipment of being stored in 5 that solar energy photovoltic power system generates such as The electric power of 10KW/h.Even if this averagely generates electric power and also depends on date and time when weather is fine Section.Specifically, in the charging interval, close to sunrise or at sunset, average generation electric power is little, and The charging interval at noon near time, it is average that to generate electric power maximum.Thus, table data include according to number Detailed data according to the average generation power with the time period.

Equipment 5 obtains the date of next day based on calendar.Additionally, equipment 5 is with the equipment of being stored in 5 In sunrise and sunset time table data obtain sunrise time and the sunset time of next day.Sunrise and day The timetable data that fall show the position (i.e. longitude and latitude) in the country at Japan or vehicle place And relation between sunrise and sunset time in this date.Such as, it is point in the morning 6 in sunrise time, And when the time started dispatched is 8 a.m., before leaving, the electricity of solar energy photovoltic power system Power generating dutation is two hours from 6 in the morning to 8 a.m..Thus, by by two hours It is multiplied by 10KW/h to calculate the charge volume of electric power, thus the charge volume of electric power is 20KW(=10KW/h × 2h).Accordingly, because the required amount of electrical power of round trip to destination is 50KW, therefore need Will be during night, i.e. before sunrise, charge 30KW(=50KW-20KW to battery).

When commercial power source is battery charging 20KW/h, need using this business merit before sunrise Rate source is that battery 4 charges 1.5 hours (=30kW/20KW/h).In this case, due to business Power source kiowatt low price in the night hours section ratio time period by day, commercial power source Charging cost at night hours, specifically at midnight, more cheap than the time by day.Thus, Equipment 5 determines that the night hours section of commercial power source is wider than one and a half hours.At commercial power source Night hours section less than 1.5 time wide time, equipment 5 prepare in step C7 charge operation plan so that Must use the night hours electric power from commercial power source that battery 4 is charged.Using business merit When charging interval needed for rate source is bigger than the night hours section of commercial power source, i.e. at commercial power source When night hours section is narrow time less than 1.5, equipment 5 prepares charging operation plan so that in night hours section Use and from the night hours electric power of commercial power source and in remaining time, section uses from this business The normal electricity (i.e. daylight hours electric power) of power source is filled with required charging and night hours electric power Difference between charging.

When equipment 5 determines and determines that in step C6 weather forecast does not represent fair weather, i.e. in step When the judgement of rapid C6 is "No", battery 4 will not be carried out fully charged by solar energy photovoltic power system. Thus, equipment 5 prepares to charge operation plan so that using from commercial power source in step C8 Battery 4 is charged by night hours electric power.In this case, needed for using commercial power source Charging interval bigger than the night hours section of this commercial power source time, equipment 5 prepare charging operation plan So that using from the night hours electric power of commercial power source and in residue in described night hours section Time period uses the normal electricity (i.e. daylight hours electric power) from commercial power source to be filled with required charging And battery 4 is charged by the difference between the charging of night hours electric power.

Equipment 5 determines in step C2 whether user has pressed charge button of travelling frequently, i.e. equipment 5 determines Whether user opens the charge switch for travelling frequently.Additionally, equipment 5 is "No" in the judgement of step C2 Time in step C4, determine whether next sky is working day.When user opens and travels frequently charge button, I.e. when the judgement of step C2 is "Yes", or when next sky is day off, i.e. in step C4 Judgement when being "Yes", proceed to step C3.In step C3, equipment 5 provides every day Commuting time.Then, step C6 is proceeded to.In step C7 and C8, equipment 5 is with weather forecast Based on prepare charging operation plan.When next sky is not working day, in next sky be i.e. holiday or During person day off, i.e. when the judgement of step C4 is "No", proceed to step C5.In step C5 In, equipment 5 estimates the time started driven based on the driving history of holiday.Then, proceed to Step C6.In step C7 and C8, equipment 5 prepares the operation plan that charges based on weather forecast.

When weather forecast in next day represents cloudy or rainy day, solar energy photovoltic power system is substantially Battery 4 is not charged.In this case, the charging from solar energy photovoltic power system is basic On be zero.Then, equipment 5 prepares charging operation plan so that farthest using from business Battery 4 is charged by the night hours electric power of power source.Equipment 5 suppose user in the rainy day or When operating rain brush in the case of cloudy weather and/or turn on lamp and/or the operating air conditioning system of vehicle, need Prepare to charge operation plan to increase the electric power consumption amount estimated.

Thus, based on this charging operation plan, farthest utilize solar energy photovoltic power system Battery 4 is charged, when being insufficient to from the charge volume of solar energy photovoltic power system, business merit Rate source uses the deficiency of night hours supply of electric power charge volume, and additionally, is sending out from solar photovoltaic Electricity system charge volume and from commercial power source use night hours electric power charge volume be insufficient to Time, use normal time electric power (i.e. daylight hours electric power) from commercial power source, battery 4 to be filled Electricity.

Fig. 5 shows the example of charging operation plan.

In Figure 5, use night hours electric power from commercial power source pair from 1:00 in morning to 2:30 in morning Battery 4 is charged.Utilize solar energy photovoltic power system to battery 4 from 6:00 to 8:00 in the morning in the morning It is charged.Destination is driven to 9:00 vehicle in the morning from 8:00 in the morning.

Equipment 5 switches electric power source selector 3 so that at solar energy photovoltic power system and commercial power Between source, switching is for the electric power source being charged battery 4.

When actual charged electrical quantity of power is the least in this time period, solar photovoltaic in this time period Battery 4 is charged by electricity generation system, and equipment 5 is automatically switched to business from solar energy photovoltic power system Industry power source.Thus, even if weather forecast makes a mistake, equipment 5 also protects battery 4 from charging Impact that amount is not enough is so that vehicle normal driving.

Additionally, the next one drive scheduling day be next day after one time, in this next sky only by Battery 4 is charged by solar energy photovoltic power system, and then, navigator 5 can be with at this It is prepared in this next sky based on the charged electrical quantity of power of the time battery after the sunrise of next day After one day and the new charging operation plan of this next day.

In the present embodiment, it is thus achieved that following effect.

Navigator 5 is with the time of advent of the estimation of next driving time inputted by user and purpose Obtain based on ground and drive the electric power consumption amount of required estimation in the next time.Drive with the next one Based on sailing sunrise time of time and sunset time and weather forecast, until during the beginning of scheduling Before between, equipment 5 is formed and uses solar energy photovoltic power system to carry out battery 4 for farthest The charging operation plan of charging.Due to equipment 5 be controlled with according to charging operation plan to battery 4 It is charged, reduces charging cost.Additionally, at the charging electric work from solar energy photovoltic power system Rate amount is compared to the electric power consumption amount hour of the required estimation of driving time next time, from commercial power Battery 4 is charged by source.Thus, substantially ensure that the electrical power for driving time next time.

Owing to using night hours electric power that battery 4 is charged by commercial power source, therefore reduce Charging cost.

Additionally, equipment 5 considers that sunrise time of current location and sunset time prepare charging scheduling meter Draw, and therefore, even if all maximum journey when being arranged on any longitude and latitude in the current location of vehicle Utilize solar photovoltaic generating that battery 4 is charged degree.

Owing to equipment 5 includes the function for obtaining current location information and/or weather forecast, therefore can Enough it is readily available current location information and weather forecast.

The 3rd embodiment will be explained with reference to Fig. 8.In the first embodiment, obtain according to from map datum The angle of inclination of road obtained and the existence of traffic lights perform for calculating the next use at vehicle The method of the electric power consumption amount estimated in.But, the data accuracy from map datum may It is insufficient to.Specifically, the map datum being stored in navigator 5 is used to obtain about vehicle A part for the route the most not run over or whole information of this route.But, navigator 5 In map datum be likely not to have preparation for calculating electric power consumption amount.Thus, it is possible to can be improper Ground calculates the electric power consumption amount estimated.

In the present embodiment, in order to improve the counting accuracy of the electric power consumption amount of estimation, from outside System obtains information.Specifically, recently, it is provided that have communication equipment for collecting vehicle Detection (probe) vehicle of driving information.Detection vehicle in communication equipment always with information centre's coupling Close so that information centre's real-time collecting and analyzing from the driving information of multiple detection vehicles.Then, The information of such as traffic congestion information and rainy information is sent to each vehicle by information centre.

The information collected by detection vehicle includes actual electric power consumption and the driving of this detection vehicle Route and the behaviour in service of vehicle.This information is uploaded to information centre.Thus, in information centre Detection vehicle information database storage about this detection vehicle actual electric power consumption information and The drive route of this detection vehicle and behaviour in service.The actual electric power consumption being stored in information centre Amount data are for calculating the electric power consumption amount of estimation.Specifically, by the type of such as vehicle, take advantage of The behaviour in service of quantity, the weight of luggage and the driving performance of visitor uploads to information centre.Then, When the behaviour in service of vehicle is identical with detection vehicle, the navigator 5 in vehicle is downloaded and is stored in this Electric power consumption amount data in information centre.Thus, navigator 5 uses to be downloaded from information centre Actual electric power consumption data calculate estimate electric power consumption amount.Thus, equipment 5 is by this spy The actual electric power consumption data of measuring car is processed as the data prepared by the navigator 5 of vehicle. In such a case, it is possible to the actual electric power consumption data obtained from information centre is registered as by The information that navigator 5 obtains.

Making of vehicle is detected in detection vehicle information data in the behaviour in service uploaded from navigator 5 With situation inconsistent time, information centre determine the behaviour in service uploaded from navigator 5 whether with detection The behaviour in service of the detection vehicle in vehicle information database is similar to.With upload from navigator 5 When the behaviour in service of the detection vehicle that behaviour in service is similar is stored in detection vehicle information database, lead Boat equipment 5 downloads the actual electric power consumption data of this detection vehicle from detection vehicle information database. The actual electric power consumption that navigator 5 is downloaded from information centre by making compensation factor be multiplied by is counted Calculate the electric power consumption amount estimated.Difference between compensation factor with vehicle and detection vehicle is corresponding. Specifically, when the behaviour in service of vehicle is of substantially equal with the behaviour in service of detection vehicle, will detection The actual electric power consumption of vehicle is used as the electric power consumption amount estimated.Behaviour in service base at vehicle In basis with detection vehicle behaviour in service inequal time, will detection vehicle actual electric power consumption It is directly used as the electric power consumption amount estimated.In this case, by making compensation factor be multiplied by detection The actual electric power consumption of vehicle obtains the electric power consumption amount estimated.Even if being vapour at detection vehicle When oil drives vehicle and diesel powered vehicle rather than electric vehicle and motor vehicle driven by mixed power, can be with this Plug-in vehicles is estimated based on the actual energy consumption of gasoline-powered vehicles and diesel powered vehicle The electric power consumption amount estimated.

The example being used for calculating the general equation of the electric power consumption amount of the estimation of plug-in vehicles is represented As follows.

(EST E P CON AMOUNT)=(ACT E PCON AMOUNT OF PROBE V) * (VEH CH X) * (LOAD FACT Y) * (DRI CH Z)

Here, term " EST E P CON AMOUNT " represents the electric power consumption amount estimated, art Language " ACT E P CON AMOUNT OF PROBE V " represents the actual electric power of detection vehicle and disappears Consumption, term " VEH CH X " represents vehicle feature factor X, term " LOAD FACT Y " Represent load factor Y, and term " DRI CH Z " represents driving performance factor Z.

When type at vehicle is equal to the type of detection vehicle, vehicle feature factor X is 1.At vehicle Weight less than the weight of detection vehicle time, vehicle feature factor X is arranged model between zero and one In enclosing.When weight at vehicle is more than the weight of detection vehicle, vehicle feature factor X is set to greatly In 1.

Passenger in vehicle and the weight of luggage less than in detection vehicle during the weight of passenger and luggage, Load factor Y is arranged in the range of between zero and one.Passenger in vehicle and the weight of luggage When being more than the weight of passenger and luggage in detection vehicle, load factor Y is set greater than 1.

Secondary less than the repetition of the acceleration of detection vehicle and deceleration in the acceleration of vehicle and the number of repetition of deceleration During number, driving performance factor Z is arranged in the range of between zero and one.In the acceleration of vehicle with subtract When the number of repetition of speed is more than the number of repetition of the detection acceleration of vehicle and deceleration, by driving performance factor Z It is set greater than 1.Additionally, the number of repetition turned in the operation of vehicle is less than the behaviour at detection vehicle During the number of repetition turned in work, driving performance factor Z is arranged in the range of between zero and one. The number of repetition turned in the operation of vehicle is more than the number of repetition turned in the operation of detection vehicle Time, driving performance factor Z is set greater than 1.Here, suppose that drive vehicle and detection vehicle traveling On identical road, grasp with the acceleration obtained by onboard sensor etc. and deceleration mode and/or deflecting roller Driving performance is determined based on making angle mode.

When having downloaded the information about detection vehicle, above-mentioned correction can be performed by navigator 5. Alternatively, navigator 5 to information centre upload the passengers quantity in the weight about vehicle, vehicle, The information of the weight etc. of luggage.Then, information centre calculate correction factor, and navigator 5 from Information centre downloads correction factor or result of calculation.Thus, equipment 5 calculates the electrical power estimated and disappears Consumption.

When vehicle is along the route running of search, reference Fig. 8 is explained the electricity being used for calculating estimation The computational methods of power consumption.When vehicle is once along the route running of search, i.e. in step D1 Judgement when being "Yes", by making factor of safety and actual electric power consumption now in step D3 It is multiplied and obtains the electric power consumption amount of estimation.In this case, for calculating the electrical power of estimation The whole road from the starting point to the destination that the search pattern of consumption once can travel equal to vehicle Line.Alternatively, the search pattern of the electric power consumption amount for calculating estimation can be that vehicle was once gone A part for the route from the starting point to the destination sailed.At vehicle also not along the route row of search When sailing, i.e. when the judgement of step D1 is "No", in step d 2, in equipment 5 or information The heart determines that whether the detection vehicle data in detection vehicle information database is for calculating the electrical power of estimation Consumption.Specifically, equipment 5 or information centre determine the behaviour in service of vehicle the most substantially It is equal to or is similar to detect the behaviour in service of vehicle, and travel in same routes at detection vehicle Time, the actual electric power consumption data of detection vehicle is registered in data base.In registration reality During electric power consumption amount data, i.e. when the judgement of step D2 is "Yes", pass through in step D4 Make the correction factor corresponding with behaviour in service be multiplied with the actual electric power consumption of detection vehicle to count Calculate the electric power consumption amount estimated.

Unregistered with and during the corresponding actual electric power consumption of search pattern same routes, i.e. exist When the judgement of step D2 is "No", similar with first embodiment, with from map number in step D5 According to the angle of inclination of this road obtained and estimate along calculating based on the traffic lights quantity of this road The electric power consumption amount of meter.Navigator 5 prepares the next one based on the electric power consumption amount estimated Charging operation plan.

In the present embodiment, navigator 5 with by travel with the detection in search pattern same routes The electric power consumption amount of estimation is obtained based on the actual electric power consumption data that vehicle is collected.Equipment 5 Next one charging operation plan is prepared based on the electric power consumption amount estimated.Thus, improve and estimate The estimation degree of accuracy of the electric power consumption amount of meter.Thus, adequate preparation is used for driving plug-in vehicles Be filled with amount of electrical power, so that preventing the deficiency being filled with amount of electrical power.Thus, equipment 5 determines Prevent use commercial electrical power source rather than solar energy photovoltic power system carry out overcharge.

Additionally, when vehicle once travels on search pattern, equipment 5 uses now actual electric work Rate consumption calculates the electric power consumption amount of estimation.Thus, the electrical power more improving estimation disappears The estimation degree of accuracy of the calculating of consumption.

The multiple detection vehicle information data storings similar or equal with the behaviour in service of vehicle are being existed Time in the data base of information centre, it is possible to use the meansigma methods of multiple detection vehicle information data is as spy Survey vehicle information data.
